USB hosts hubs transceivers Forum Discussions

Hello,

I am wondering if this USB component: CYUSB3314-88LTXC has Android and Linux Drivers that are associated with it. My company is planning on implementing this component with a TV box device based on Android and Linux.

If anyone knows the answer, please let me know if these drivers exist and/or how I can obtain them.

Thanks!

Hi, I am using the CY7C65642 hub chip that is interfaced to the Jetson NANO module. The schematic is as shown below -

It shows the relevant chip (USB2.0 hub). There is a power switch connected as shown below -

Now I am connecting a T261 module to one of the Type A ports on the board. Sometimes on a soft reboot the T261 is not detected and the CY7C keeps reseting the EN pin to the current switch.

But, if I place the T261 along with even with a mouse or wifi dongle it magically works. Any feedback on this ? Have you observed this kind of behaviour,

I need the reference schematic of CYUSB3304-68LTXC under Candence. Can you provide it to me? I didn’t find the reply I wanted to ask in the forum

We are using the CYUSB4347 in one of our projects, we are able to see it in the Windows 10 Device Manager:

Device USB\VID_04B4&PID_2347\5&12ec354d&0&1 was configured.

Driver Name: usbhub3.inf

Class Guid: {36FC9E60-C465-11CF-8056-444553540000}

Driver Date: 11/08/2018

But we cannot “Get Status” via the EZ-USB HX3PD Configuration Utility:

Querying dock status

Opening handle to dock

No dock devices found

Connecting device failed

Failed to connect device

HX3PD get status failed

Consequently we are not able to update the firmware. Any pointers what to try or look at to solve this?

Thanks,

Brett

Hi all,

I have two cy7c65642 hubs arranged in a cascaded manner. The downstream hub is not able to connect in both Windows and Ubuntu, with the following messages respectively: "not enough power on the USB hub" and "can't connect bus-powered hub to this port".

The hubs are configured for bus power, i.e. SELFPWR pins pulled low.

I couldn't find anything in the datasheet explicitly requiring self-power for cascading hubs. Is this required? As such, will pulling the SELFPWR pins on both hubs high fix this issue?

NB: I connected the supply line to an external power supply, and measured current was < 200 mA

The default max power of 100mA was also increased to 500 mA in the EEPROM config.

Cheers

In case of 2 port Hub CY7C65634 configured in individual power mode.

the PWR# pin should be de-asserted after an overcurrent event. but on which port will this pin respond? OVR#[1] or OVR#[2] ?

您好，

客户在调试 cy7c65215的时候，在CY的评估板上测试是OK的，把相同的配置文件，下载到客户自己板子上后，测试发现无法识别这个芯片，请问这是什么原因？谢谢

Hello

The customer is looking for a hub that can use three DS's with USB 2.0.

(CYUSB2304-68?)

They have used the CYUSB3302-68LTXC before.

●I think the two devices are pin compatible, is this correct?

●Is it correct to use CYUSB2304-68 if I want to use a hub with more than 3 USB 2.0 ports?

（Are there other candidates for Cypress devices?）

Best Regards

I'm looking for appropriate solution like Type C PD hub.

Currently, spec is below.

-Charging : Type C charging / Type A charging(BC1.2 CDP) from TA(Type C UFP port)

-USB data : USB 2.0 communication between Type C host and Type A device

I had reviewed what is appropriate solution for.

The similar solution is CCG3 CTD solution. but I think it's heavy a little.

Among PD hubs, HX3C is supporting 2 DRP role. but PD Port2 was using DFP port on HX3C Dock reference design.

If you know that there is appreciate solution. let me know and guide.

Regards.
